hereafter is a good example of this:

He will say: "What number of years did you stay on earth?" They will say:
"We stayed a day or part of a day, but ask those who keep account." He
will say: "You stayed not but a little, if you had only known!" (Surat al-
Muminun: 112-114)
In some other verses Allah states that time may flow at different paces
in different settings:
Yet, they ask you to hasten on the punishment! But Allah will not fail in His
promise. Verily a day in the sight of your Lord is like a thousand years
of your reckoning. (Surat al-Hajj: 47)
The angels and the spirit ascend unto Him in a day the measure whereof
is (as) fifty thousand years. (Surat al-Ma'arij: 4)
He rules (all) affairs from the heavens to the earth: in the end will (all affairs)
ascend to Him in a day the measure of which is a thousand years of
what you count. (Surat al-Sajda, 5)
These verses are clear expressions of the relativity of time. That this
result, which was only recently understood by scientists in the 20th centu-
ry, was communicated to man 1,400 years ago in the Qur'an is an indica-
tion of the revelation of the Qur'an by Allah, Who encompasses the whole
of time and space.
Many other verses of the Qur'an reveal that time is a perception. This
is particularly evident in the stories. For instance, Allah has kept the
Companions of the Cave, a group of believing people mentioned in the
Qur'an, in a deep sleep for more than three centuries. When they awoke,
these people thought that they had stayed in that state but a little while,
and could not reckon how long they had slept:
Then We drew (a veil) over their ears, for a number of years, in the Cave,
(so that they heard not). Then We raised them up that We might know which
of the two parties would best calculate the time that they had tarried. (Surat
al-Kahf: 11-12)
Such (being their state), We raised them up (from sleep), that they might
question each other. Said one of them, "How long have you stayed (here)?"
They said, "We have stayed (perhaps) a day, or part of a day." (At length)
they (all) said, "Allah (alone) knows best how long you have stayed here…"
(Surat al-Kahf: 19)
